The Mad Hatter (Jervis Tetch) is a supervillain appearing in comic books published by DC Comics, commonly as an adversary of the superhero Batman. He is modeled after the Hatter from Lewis Carroll's novel Alice's Adventures in Wonderland, a character often called the "Mad Hatter" in adaptations of Carroll.

He is one of Batman's most enduring enemies and belongs to the collective of adversaries that make up Batman's rogues gallery.
